subject: Screen Printing Process Four Note [print this page] The division of labor by the people Cooperation Jointly completed printing, only the working procedure of the next procedure is responsible for and do their own process of self, self-examination of work, strict quality control to produce the web version of printed customer satisfaction. The screen, ink and printing good match between these three is a prerequisite for good print. Plate quality directly determines the merits of printing quality, printing only the quality of the test plate, but in the quality of the stability of the plate, because of printing workers complacent, the same can not be the ideal print, but will result in more waste, appear defective or scrap.
Printed in bulk, before fixing the print screen into India ink test, inspection copy level graphic layout, ink, ink film thickness, size, precision register. If register less precision, the framework can be adjusted in front of the fine-tuning knob; if ink hue does not check for the wrong ink, and immediately replaced; if pains to depict the bad, can be used Solvent Graphic part of the clean plate, so that ink on the substrate through the performance and the wettability of a certain improvement; if the order of harmonic level graphic big difference, they should immediately replace the print screen. In the printing process is important to note the following points.
(1) ground to see the rules. Box at the time of printing but due to constant movement back and forth to make plates and frames subjected to impact from running and vibration, relatively small displacement between them, overlay appeared inaccurate and adversely affect the appearance of product quality. So look to ground rules, promptly found and adjusted.
(2) always check the proofs. Found that lack of ink blot print, immediately wipe with a clean cotton cloth screen. Most of this is due to a broken plate on the sticky plastic film or crust drying ink caused plug the screen. If it is found or become uneven Talking about the ink, may be the ink viscosity is too great and should be shut down immediately diluted with a solvent viscosity of ink, while gasoline clean layout of the graphics part, to prevent ink penetration or blocking network in order to facilitate continuous work.
(3) to semi-finished stacked neatly. In the semi-stacking process, must keep paper stacked on both sides of sagging. Otherwise the paper because of their gravity to form the bow, paper both sides of the upturned rather than flat, transfer printing paper as the difficulties often occur off Zhang phenomenon. Do not normally stack of paper that can be used flat cardboard mat, while the height of stacks of paper to paper, often with sub-sector adjustment knob to adjust in order to deliver smooth paper, printing process smoothly.
(4) drying device leaves some damage as long-term use, some places run out of sync with the host, is often an arbitrary printed sheets of paper the phenomenon of the shelves. At this point it should be eye grassland, once the bottom sheets from chaos aside, the best non-membrane surface relative to ink, so as not to cause defective or scrap the bad stick.
Therefore, only the importance of various aspects affecting the printing quality, can print out the fine print, enhance yield, reduce consumption and increase efficiency, so the competition in the market in an invincible position.
